Also included are a second slide rail 307 and a second motorized slider 308; a second sliding rail 307 is fixedly connected to the third fixing plate 306; four second electric sliders 308 are slidably connected to the second slide rails 307, each second electric slider 308 is fixedly connected with the adjacent extrusion plate 309, the extrusion plate 309 is driven to move along with the adjacent baffle 303 through the second electric sliders 308, the screening plate 1001 is extruded, gaps between the baffle 303 and the screening plate 1001 are prevented from being oversized, grains without metal foreign matters fall into the arc-shaped grooves, and subsequent screening workload is reduced.
Also included is dust cloth 310; a piece of dustproof cloth 310 is fixedly connected between every two adjacent baffles 303; the dust cloth 310 covers the upper parts of grains between two adjacent baffles 303, so that dust raised in the process of pushing the grains to the discharge groove 4001 of the conveying frame 4 by the pushing block 305 is prevented from entering air, and the working environment is prevented from being influenced.
The following describes the above process in detail: when the extrusion block 3 moves above the position where the metal foreign matters are located, the second electric sliding block 308 is controlled to drive the extrusion plate 309 to synchronously move along with the adjacent extrusion blocks 3, then the first driving piece 103 is controlled to drive the extrusion block 3 to move downwards, and the lower screening plate 1001 is extruded to deform the screening plate 1001 to form an arc-shaped groove until the baffle 303 and the extrusion plate 309 are mutually extruded, so that the gap between the baffle 303 and the screening plate 1001 is prevented from being too large, grains without the metal foreign matters drop in the arc-shaped groove, thereby improving the metal foreign matters screening effect, at the moment, the telescopic rod 304 and the pushing block 305 are positioned at the left side of the arc-shaped groove, the telescopic rod 304 is in a compressed state, then the third driving piece 302 is controlled to extend and retract at the front side and the rear side, thereby driving the adjacent two baffles 303 to swing at the front side and the rear side respectively, and the grains at the two sides of the metal foreign matters on the screening plate 1001 are pulled out, because the telescopic rod 304 is rotationally connected with the two adjacent baffles 303, when the two baffles 303 swing towards the front side and the rear side respectively, the telescopic rod 304 and the push block 305 gradually move towards the right side of the arc-shaped groove and push grains, so that grains are prevented from accumulating in the arc-shaped groove, meanwhile, because the push block 305 is U-shaped and is made of deformable materials, the push block 305 always keeps contact with the arc-shaped groove through the telescopic rod 304, grains in the arc-shaped groove are scraped to the greatest extent, meanwhile, the falling speed of the grains in the arc-shaped groove is accelerated, the working efficiency is improved, meanwhile, the grains in the arc-shaped groove and the metal foreign matters are blocked through the bulge 30501 on the push block 305, so that the metal foreign matters are prevented from passing over the push block 305 in the scraping process, and are prevented from remaining on the screening plate 1001, so that the metal foreign matters are prevented from being screened out, and meanwhile, in the process that the push block 305 scrapes the grains, the dust cloth 310 covers the upper parts of grains between two adjacent baffles 303, so that dust raised in the process of pushing the grains to the discharge groove 4001 of the conveying frame 4 by the pushing block 305 is prevented from being diffused into surrounding air, and the working environment is prevented from being influenced.
Example 4
Based on the embodiments 1-3, as shown in fig. 1, 2 and 9-11, a squeeze roll 402 is included; two squeeze rollers 402 are rotatably connected to each of the two adjacent squeeze plates 309, and the two adjacent squeeze rollers 402 are rotatably connected by gears; two adjacent squeeze rollers 402 are horizontally arranged, and an electromagnet is arranged on the outer side of each squeeze roller 402; each squeeze roller 402 is located at the right lower side of the arc-shaped groove formed by the screening plate 1001 of the conveyor belt 1.
Also included is a servo motor 401; each extruding plate 309 positioned at the front side below the extruding block 3 is fixedly connected with a servo motor 401, and the output shaft of each servo motor 401 is fixedly connected with the adjacent extruding rollers 402, and the servo motor 401 drives the adjacent two extruding rollers 402 to rotate, so that grains adhered with metal foreign matters are separated.
Also comprises a driving belt 501 and a squeeze bar 502; each squeeze plate 309 is rotatably connected to a belt 501, and each belt 501 is rotatably connected to an adjacent squeeze roller 402 by a belt; a plurality of extrusion strips 502 are fixedly connected between two adjacent driving belts 501, and a plurality of balls with different sizes are fixedly connected on each extrusion strip 502.
The spheres on each extrusion strip 502 are distributed in a staggered way; the extrusion strips 502 are arranged in a staggered mode, when the extrusion strips 502 extrude the arc-shaped grooves formed by the screening plates 1001, the arc-shaped grooves generate tilting changes of different degrees, and therefore metal foreign matters are prevented from being blocked on the arc-shaped grooves and cannot fall down, and the screening effect on the metal foreign matters is further improved.
The following describes the process of separating metallic foreign matters and the process of preventing metallic foreign matters from being stuck in detail: when the environment is moist, adhesion each other after the part cereal is wet, lead to part metal foreign matter to be wrapped up in between the caking cereal at the in-process of cereal adhesion each other, when ejector pad 305 pushes away cereal from the arc groove that screening plate 1001 of conveyer belt 1 formed into the row silo 4001 of transport frame 4, cereal from the arc notch drop, this moment control servo motor 401 drives adjacent two squeeze rolls 402 and rotates, roll the cereal of caking, thereby make the metal foreign matter that is wrapped up in the cereal separate with cereal, prevent simultaneously that cereal from following metal foreign matter and dropping in the storage tank of transport frame 4, reduce material loss, meanwhile, open automatically controlled switch, adsorb the metal powder granule that contains in cereal through the electro-magnet on squeeze roll 402 surface, and the size of the electro-magnet magnetic force of squeeze roll 402 only can adsorb the metal foreign matter of granule volume less than cereal, the particle volume is greater than the metal foreign matter of cereal will follow filter screen 5 landing to the storage tank of transport frame 4, at the same time, the conveyer belt 501 of arc groove below follows adjacent squeeze roll 402 and rotates, thereby make squeeze strip 502 and squeeze down the groove that screening plate 1001 forms, and each roll down, and prevent that the profile of each roll from rolling down the roll up the arc groove from being different, thereby, further change the effect is improved because of the profile of metal foreign matter is down on the roll profile is difficult to change.
